Definitions
- the invention relates to a hose for guiding fluids according to the preamble of claim 1.
- Reinforced tubes are well known in the art. They are used, for example, for transporting fluids in the general industrial sector, in the automotive sector, e.g. used as pressure hoses for motor vehicles, or for drinking water and for the transport of water in commercial or private garden management.
- Armored hoses are for example from the DE-OS 34 08 251 or even the DE-OS 29 38 833 known.
- reinforcing elements are wound or braided around the fluid-carrying hose layer without the intersecting reinforcing elements being interlinked.
- Such thread-reinforced hoses have the disadvantage that they tend to kinking, if a certain amount of laying radius is reached. Under tension, the hose closes more and more, until it finally becomes unusable.
- the EP 0 527 512 A1 shows a tube with a reticulated reinforcement, in which the reinforcing fibers are aligned parallel or perpendicular to the tube axis.
- Knitted fabric is knitted or knitted fabric, in which the threads in mesh loops (stitches) intertwined or knitted together.
- the reinforcing elements along the tube longitudinal axis form a zig-zag line, wherein spaced, adjacent reinforcing elements are entwined at their connection points at least once in each other.
- Such a reinforcement allows the hose a certain "breathing" when pressurized. Due to its structure, the reinforcement has a very open structure analogous to the shape of a conventional chain link fence, so that the corresponding hose has a high degree of flexibility and thus does not bend so easily.
- the tube opens under train again and thus allows the further flow of the fluid.
- a problem with this prior art is that the adaptation of the reinforcement to the conditions of the particular application is only possible to a limited extent.
- the invention has for its object to provide a hose with the features described above, the reinforcement can be flexibly adapted to the particular application.
- the reinforcing elements may be constructed from textile (for example cotton and / or synthetic fibers) and / or metallic and / or ceramic and / or polymeric threads, whereby at least two different materials of the aforementioned type are combined with one another, e.g. Reinforcing elements of textile threads with reinforcing elements of ceramic threads or e.g. metallic threads with reinforcing elements of polymeric threads.
- Suitable polymeric materials are, in particular, polyesters or PVC.
- mineral e.g. Glass, and / or carbon and / or aramid and / or basalt fibers as thread material, optionally in combination with one or more of the aforementioned thread materials.
- the combination of different materials for the reinforcing elements results in a correspondingly hybrid structure of the reinforcing layer, so that, for example, the degree of reinforcement, the flexibility, the buckling stability and also the production costs can be made very variable via this choice of material.
- all reinforcing elements have a hybrid structure with an inner layer and an outer layer made of different materials.
- the hybrid idea is already realized in a single reinforcing element by having a multilayer structure with different materials.
- the outer layer serves to weld the reinforcing elements at their connection points and / or to weld the reinforcing layer to the inner and / or outer tube layer.
- the position of the individual reinforcing elements is fixed to each other or made an intimate connection of the reinforcing layer to the inner and / or outer tube layer, so that it does not lead to an undesirable displacement of the reinforcing structure against the tube layers or reinforcing elements within the use of the hose the reinforcing layer comes.
- a reliable function of the reinforcing layer is ensured even after a longer period of use of the hose.
- the welding is expediently ensured by a corresponding heating of the components, for example by the heat still present in the inner tube layer immediately after its extrusion.
- the outer layer of the reinforcing elements may contain PVC. In a particular embodiment of the invention, the outer layer consists of PVC.
- the inner tube layer and / or the outer tube layer plastic preferably contain PVC.
- the inner and / or the outer tube layer of a transparent, so transparent or translucent material.
- a transparent outer tube layer allows the additional use of the reinforcing layer as designerisches element of the hose.
- one or more further tube layers can be provided in addition to the layers mentioned between the inner and outer tube layers.
- the reinforcing elements can form a zigzag line along the hose longitudinal axis, wherein adjacent reinforcing elements are intertwined at their connection points at least once.
- the structure of the reinforcing layer can be designed, in particular, analogously to the shape of a conventional wire mesh fence.
- the reinforcing layer has diagonal lines formed by the reinforcing elements, which preferably enclose an angle of 44 ° to 64 °, preferably 50 ° to 58 °, with the tube longitudinal axis.
- Particularly preferred here is a reinforcement angle of about 54 °, which corresponds to the so-called neutral angle in Schlaucharmtechniken with respect to longitudinal to transverse extent at a pressurization.
- the reinforcing elements extend longitudinally and transversely to the tube longitudinal axis, ie analogous to the already mentioned EP 0 527 512 A1 essentially parallel and perpendicular to the tube axis. This grid structure is advantageous for certain applications.
- the hose according to the invention described above can be used for a wide variety of applications. In general, it is suitable for a wide variety of industrial applications and is mainly used in motor vehicles as a pressure hose or for drinking water transport and for the transport of water in commercial or private garden management.
- FIG. 1 shows a hose for guiding fluids with an acted upon by the fluid 1 extruded inner layer 2 made of plastic, preferably plasticized, a reinforcing layer 3 and a reinforcing layer 3 enclosing, protective outer tube layer 4 made of plastic, preferably plasticized, also produced by extrusion becomes.
- the reinforcing layer 3 has a plurality of reinforcing elements 5, 5 ', which are connected to one another like a mesh.
- the reinforcing layer 3 can - depending on the size of the free hose cross-section and application - for example, be composed of 8 to 20 reinforcing elements 5, 5 ', preferably 12 to 16.
- In FIG. 1 are adjacent reinforcing elements 5, 5 'made of different materials.
- the reinforcing element 5 consists of a polyester thread, while the reinforcing element 5 'consists of a metal thread.
- the FIG. 1 It can also be seen that the reinforcing elements 5, 5 'along the tube longitudinal axis x form a zig-zag line, wherein adjacent reinforcing elements 5, 5' at their connection points 6 are intertwined at least once in each other (s Fig. 1 ).
- the reinforcing layer 3 has an open structure with diamond-shaped passages a analogous to the shape of a conventional chain link fence. In this case, the respectively adjacent reinforcing elements 5, 5 'are linked together.
- the reinforcing element 5 is both with the reinforcing element 5 'in Fig.
- FIG. 1 It can also be seen that the reinforcing layer 3 of the reinforcing elements 5, 5 'formed diagonal lines 7, which with the hose longitudinal axis x an angle of about 54 °, the so-called neutral angle with respect to longitudinal to transverse extent when pressurized includes.
- the reinforcing elements 5 have a hybrid structure with an inner layer 8 and an outer layer 9 of different materials.
- the outer layer 9 is formed as an impregnation of the inner layer 8 consisting of a polyester thread.
- the outer layer 9 is used for welding the reinforcing elements 5 at their connection points 6 and for welding the reinforcing layer 3 with the inner tube layer 2 and the outer tube layer 4.
- both the outer layer 9 and the inner tube layer 2 and the outer tube layer 4 are made PVC made.
